' Specification of Letters Patent.

- Patented Oct. 3, 1916,

To all whom it may concern:

- Be it known that we, WILLIAM L. CASH and IoN B. CRoWE, citizens of theUnited States, and residents of Graham, in the county of Muhlenberg andState of Kentucky, have made an Improvement in Carbid-Can Tops, of whichthe following is a specification.

Our present invention is an improvement upon the carbid can for which wehavereceived Letters Patent, No. 1,164,465, dated Dec. 14, 1915.

The improvement pertains particularly to i the means for locking the topor discharge spout of the can to the body of the latter detachably.

The details of construction, combination, and operation of the inventionare as hereinafter described, and illustrated in the. accompanyingdrawing, in which- Figure 1 is a vertical section of the canv andholder. Fig. 2 is a partial section at right angles to Fig. 1 and takensubstantially on the line 2-2 of the said figure, the locking devicesbeing engaged with the flange of the can body. Fig. 3 is a perspectiveview of the cover looking from below, the locking devices being showndisengaged. Fig. 4 is a similar view of one of the looking' members.

The cylindrical body 1 of the carbid' holder is pivoted between thevertical arms or supports 2 which are secured upon a flat base 3 asdescribed and illustrated in our aforesaid patent. The body of the topor cover 4 has substantially the form of a truncated cone. The nozzle orspout 5 has a cap 6 as in our original invention. Two (2) spring lockingdevices are applied to the conical cover 4; The chief element of theseis represented detached in Fig. 4, the same being a rod 7 having a crosshandle 8 at its upper end and a lateral prong or arm 9 at its lower end.This device is held rotatably in a vertical, tubular guide 10, which isfixed in an annular bracket 11 that projects through the conical cover.and is soldered in place. tubular guide is cut away on the side adjacent to the pendent flange 12 of the cover. The portion thus cutawayprovides space forthe rotationof the arm 9 of the locking The lowerend of the device. The pendent portion 13 of the tubular guide isnotched at its end as shown in Fig. 8. A spiral spring 14' encircles theportion of the rod of the locking device that projects above the tubularguide 10.

The operation of the locking devices will now be understood. Asshown inFig. 2, the

two sets of locking devices are arrangedon opposite sides of the top orcover; The said top 4 has a horizontaljflange l5 and a vertical flange12 is pendent from the latter. In applying the can top tothe can bodyits vertical flange abuts the annular flange 16 of the body and thehorizontal flange 15 of the cover rests upon the body flange 16. Beforethe can cover can be thus applied the locking devices must be adjustedin the position represented in Fig. 2; that is to say, the rods 7 arepushed down against the tension of the springs 14 and .at the same timerotated so that their lateral arms 9 will" be turned under thedownwardly projecting ends 13 of the tubular guides and engage in thenotches with which the latter are provided. In this position, that is tosay, when the horizontal arms of the lockingdevices are turned inwardand locked. with the tubular guides, it is obvious they do not interferewith the insertion or removal of the cover 4; but when the cover hasbeen set in place, as indicated in Fig. 2, the locking devices 7 aredisengaged from the notches of the tubular guides and turned half wayaround, by which they assume the position indicated in Figs. 2 and 8.The springs 14 are attached .at their respective ends to the rod 7, and,consequently, when the rods are pressed down to-clear the notches 13 ofthe pendent guides, the springs 14 will automatically rotate the lockingdevices half way around, or in other words throw them into the positionshown in Fig. 2; so that the arms 9 project under the flange 16 of thebody and thus efl'ectively lock the cover of the can to the body. Thesprings are so attached that they will hold the locking devices in thisposition, unless rotated manually with sufficient force to -overcome thetension of the springs. It is apparent that the expansion ofthe springsdraws the arms body, '55 that the cover is held tightly in place, unlessthe locking devices be manually. manipulated to effect theirdisengagement, as will be readily understood from the foregoingdescription.

To provide for more effective engagement of the locking device with thependent notched end of the tubular guides, a flat shoulder 17 is formed(see Fig. 4) at the' junction of the rod 7 with its lateral arm 9. Apiece of sheet metallS (see Fig. 3) is soldered or otherwise attached tothe inner side of the cover adjacent to its rim and projects laterallyas shown. This device serves to" prevent carbid particles from lodgingin the angle between the top and inslde wall of the head of the can, andthe device is arranged midway between the locking devices so that theoutward passage or discharge of carbid is not interferred with by theportions of the locking device that 'project'belowthe can cover.

We claim v A carbid can having a flanged head, a detachable cover, thelatter provided with ver tical tubular guides which extend below thecover and are cut away on the outer side adjacent to. the rim of thecover, hookshaped' devices which are slidable and rotatable in saidguides, spiral expansion springs applied to the upper ends of thelockingdevices exterior to the cover, the locking"devices being thusheld engaged with the head of the can when rotated to the outerposition, and in engagement with the tubular guides when rotated to theinner or outer posititon, as described.
